feat: 增强 command-guide skill，新增 UI 设计工作流指南和自动同步功能

## 主要更新

### 1. 新增 UI 设计工作流完整指南
- 新增 `ui-design-workflow-guide.md` (12KB)
- 使用 Gemini 分析 11 个 UI 设计命令文件
- 提供 4 种工作流模式详细指导：
  - 探索式设计（新概念）
  - 设计复制（模仿现有网站）
  - 代码优先导入
  - 批量生成（高容量）
- 包含架构最佳实践、性能优化和故障排查

### 2. 更新工作流模式指南
- 在 `workflow-patterns.md` 中新增 Pattern 7: UI设计工作流
- 提供三种子模式的中文示例
- 添加 UI 设计指南的交叉引用

### 3. 增强索引构建脚本
- 更新 `analyze_commands.py` 支持自动同步 reference 目录
- 新增 `sync_reference_directory()` 函数：
  - 自动删除旧的 reference 文件
  - 从 `.claude/agents` 和 `.claude/commands` 复制最新文件
  - 确保索引构建前 reference 目录为最新
- 增强统计输出，显示 reference 目录同步状态

### 4. 更新索引文件
- 重建所有索引文件（all-commands.json, by-category.json 等）
- 优化命令元数据和分类
- 同步最新的 UI 设计命令（包括新增的 import-from-code.md）

## 技术细节

**命令分类体系**:
- Orchestrators: explore-auto, imitate-auto, batch-generate
- Core Extractors: style-extract, layout-extract, animation-extract
- Input & Capture: capture, explore-layers, import-from-code
- Assemblers: generate, update

**架构原则**:
- 关注点分离：Style、Structure、Motion 独立
- Token-First CSS：使用 CSS 变量而非硬编码
- 并行执行：支持最多 6 个并发任务
